### What data can Cloudflare access when TURN is used with WebRTC?

When Cloudflare Realtime TURN is used in conjunction with WebRTC, Cloudflare cannot access the contents of the media being relayed. This is because WebRTC employs Datagram Transport Layer Security (DTLS) encryption for all media streams, which encrypts the data end-to-end between the communicating peers before it reaches the TURN server. As a result, Cloudflare only relays encrypted packets and cannot decrypt or inspect the media content, which may include audio, video, or data channel information.

From a data privacy perspective, the only information Cloudflare processes to operate the TURN service is the metadata necessary for establishing and maintaining the relay connection. This includes IP addresses of the TURN clients, port numbers, and session timing information. Cloudflare does not have access to any personally identifiable information contained within the encrypted media streams themselves.

This architecture ensures that media communications relayed through Cloudflare Realtime TURN maintain end-to-end encryption between participants, with Cloudflare functioning solely as an intermediary relay service without visibility into the encrypted content.

### Is Realtime TURN end-to-end encrypted?

TURN protocol, [RFC 8656](https://datatracker.ietf.org/doc/html/rfc8656), does not discuss encryption beyond wrapper protocols such as TURN over TLS. If you are using TURN with WebRTC will encrypt data at the WebRTC level.
